Crabapple Jelly

Ingredients

Directions

Prepare the fruit

  1. Quarter the crab apples and place them in a preserving kettle.

  2. Add enough cold water to cover the top layer of the fruit.

  3. Heat gradually and boil until the apples are soft.

  4. Transfer the mixture to a jelly bag and let it drain overnight.

Make and jar the jelly

  1. Measure the juice and add just under 1 cup of sugar for each cup of juice.

  2. Boil for 10 minutes or until a small amount jellies on a cold plate.

  3. Pour into sterilized jars and seal.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: 1-octen-3-ol (mushroom, earthy).

Apple and sugar barely smell alike, yet cooks put them together in 16,478 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Crab apples
Provide the fruit flavour and natural pectin that lets the juice set into jelly.
Sugar
Sweetens the jelly and helps it set by binding with pectin and water.

The step that matters

Boil until the jelly tests as set. Boiling too briefly leaves the jelly runny, while overcooking can make it stiff or dull. Checking a small amount on a cold plate shows whether pectin and sugar have reached the gel point.

Swap the apple

How well each one fits the dish's main ingredients (crab, sugar):

  1. Raisinfits better
  2. Lemonfits better
  3. Vanillafits better
  4. Applethe original

Fit is the average pairing score against crab, sugar. Candidates are from the same food group and used in at least 100 recipes.
